Notice: The Industry Canada label identifies certified equipment. This certification
means that the equipment meets certain telecommunications network protective,
operational and safety requirements. The Industry Canada does not guarantee the
equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equipment
must also be installed using an acceptable method of connection. In some cases, the
company’s inside wiring associated with a single line individual service may be
extended by means of a certified connector assembly (telephone extension cord). The
customer should be aware that compliance with the above conditions may not prevent
degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian
maintenance facility designated by the supplier. Any repairs or alterations made by the
user to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of
the power utility, telephone lines and internal metallic water pipe system, if present,
are connected together. This precaution may be particularly important in rural areas.
Caution: Users should not attempt to make such connections themselves, but should
contact the appropriate electric inspection authority, or electrician, as appropriate.

Introduction The Verilink T Lite CSU provides an economical solution for
providing the T1 in terface bet ween cu stom er premise s equ ipment
and T1 facilities (telco or private). Each unit is compatible with
all T1 carrier transmission equipment and is designed to comply
with all industry-standard specifications. Both the transmitted
and received 1.544 Mbps signals are conditioned.
The T Lite is an industry standard, frame transparent T1 channel
service unit. It detects and activates network initiated loopbacks,
monitors bipolar violations, and maintains pulse density of the
transmitted signal. The unit works with any T1 line format and is
transparent to framed (D4 or ESF) or unframed T1 signals. The
T Lite is transparent to line coding and can operate in either AMI
or B8ZS coding. The T Lite can transcode B8ZS signals from
the network into AMI signals for the equipment and AMI signals
from the equipment into network B8ZS signals.
The unit is designed to be wallm ounted using hook -and-loop
fasteners or “T” openings on the base (l ike a telephon e). The uni t
can also be set on a desktop.
The unit provides ALBO circuitr y on the network receive path.
The network ALBO supports a receive range from +1 to −30
decibels. The DTE supp orts DSX1 signal rang es up to 655 feet.
The unit also provides line build out (LBO) circuitry on both
network and DTE. The network transmit LBO is user selectable
in four increments (from 0 to −22.5 decibels). The DTE transmit
LBO is user selectable in five increments from 0 to 655 feet.
Features
The T Lite operates from an external VAC power source.
Network and DTE c onnections a re made thro ugh RJ-48C
connectors. The unit s have primary and secondary surge
protection on both the network and DTE side (meeting the UL
1950 requirements).
✦ Provides T1 facility interface and jitter tolerance per ANSI
T1.102, T1.403, and AT&T TR 62411
✦ Transparent to ESF-formatted data
✦ Supports framed and unframed signal formats
✦ Space-saving design can be desktop or wall mounted
✦ Standard 5-year warranty

Introduction This chapter contains information and instructions required to
prepare the Verilink T Lite for use. Included are initial inspection
procedures, mounting instructions, configuration guidelines,
connection and powering information .
Safety Summary
Unpacking
and
Inspection
This manual contains information and warnings that must be
followed to ensure safe operation and retain the equipment in a
safe condition.
This WARNING sign denotes a potential hazard to the
operator. It calls attention to a procedure or practice that, if
not correctly performed or adhered to, could result in injury or loss
of life. Do not proceed beyond a WARNING sign until the indicated
conditions are fully understood and met.
Caution: Units are susceptible to damage caused by static
electricity. Use ESD (electrostatic discharge) precautionary
measures, such as wearing electrostatic grounding straps.
This unit is carefully packaged to prevent damage in shipment.
Upon receipt, inspect the shipping container for dam age. If the
shipping con tainer or cushionin g materi al is damage d, noti fy the
carrier immediately and make a not ation on the delivery receipt
that the container was damaged (if po ssible, obtain the signat ure
and name of the person ma king delivery). Re tain the pack aging
material until verifying the contents of the shipment are complete
and the unit has been checked b oth mech anically and ele ctrical ly.
If the contents of the sh ipment are incomp lete or, if there is
mechanical damage or defe ct, notify Verilink. If the shipping
container is also damaged , or the cushioning materia l shows
signs of stress, notify the carrier of the damage as well as
Verilink. Keep the shipping materials for the carrier’s inspection.
Verilink will arrange for repair or replacement without waiting
for claim settlement.

✦ external AC power supply
✦ reference manual
✦ adhesive strip
✦ two 9-foot RJ48-to -RJ48 cabl es (part num ber 9 -1 544 -6 19 -009)
Using Adhesive Strips
1 Select a place close to an 115 VAC outlet with clearance for the
signal and power cables as well as for ba ntam test cables. The
indicators and switches should be eas ily accessible.
2 Veri fy the mounting surface is clean.
3 Cut the adhesive strip to the desired length and affix the backing
of one piece to the u nderside of the unit.
4 Attach the other a dhesive strip to the piece on the underside o f
the unit.
5 Remove the backing to expose the sticky surface.
6 Press the underside of the unit firmly against the selected place.
Using Screws
1 Select a place close to an 115 VAC outlet with clearance for the
signal and power cables as well as for ba ntam test cables. The
indicators and switches should be eas ily accessible.
2 Verti cally place two #6 sc rews 3-13 ⁄32 inches apart at th e
selected place. Leave the screws out about an eighth of an inch.

Power
Configuration
Plug the connector from the power supply into the unit. Plug the
transformer into an appropriate outlet. This applies power to the
unit.
This section describes the configuration of the T Lite. This unit
is configured using DIP switches. Refer to Figure 2-1 for switch
locations. The T Lite unit is transparent to framed (D4 or ESF)
and unframed T1 signals. It can also be configured as transp arent
to line coding and operates with AMI and B8ZS.
On power up, each unit is configured to the settings of the
option switches. Changes to the NET LBO and EQ LBO
switches do not take effect until the unit is reset. Reset the unit by
removing power from the unit and then reapplying power. The
loopback switches activate as soon as they are thrown.
